.Use the installation wizard to select the server components that you want to install and the location on your computer where you want to install them. Only the components that you choose to install are copied from the CD to your computer. If you plan to install two or more IBM Cognos 8 components on the same computer, we strongly recommend that you install them in the same installation location to avoid conflicts among ports and other default settings.
We also recommend that you do an interactive installation .
The IBM Cognos 8 server components include the following:
You can install each component on a separate computer, or on the same computer. You must install the gateway on a computer that is also running a Web server.
If you are installing IBM Cognos 8 Metrics Manager,
you must create the metric store database and at least one metric package . Next,
you must install the client components . For uninstalling instructions, see Uninstalling IBM Cognos 8.
Samples are on a separate CD in your IBM Cognos 8 product. If you want to use the samples, you must install them from the IBM Cognos 8 Business Intelligence Samples 8.4 CD.
In a distributed environment, the sequence in which you configure computers is important. Configure and start the computer with the active Content Manager first. Then configure and start the computer with the standby Content Manager, followed by the Application Tier Component computer. Configure the gateway computer last so that cryptographic keys are shared and secure communication can take place among the three components. The server specified for the External Dispatcher URI property on the gateway computer must be the last server that you start.
If you need to stop services, the sequence is important. Stop the IBM Cognos 8 service for Application Tier Components first, followed by the standby Content Manager, and then the active Content Manager.
It is important to also stop the following:
Web servers that host IBM Cognos 8 content
applications that are related to the IBM Cognos 8 service, such as Framework Manager, IBM Cognos 8 Transformer, IBM Cognos Connection, IBM Cognos Administration, and Metric Designer
any SDK applications that are running
If you are upgrading from a previous release of IBM Cognos products, you must use the upgrading steps. For information about upgrading from ReportNet or Metrics Manager, see Upgrading to IBM Cognos 8.
If you are upgrading from ReportNet or an earlier version of IBM Cognos 8, all the distributed components must be the same version of IBM Cognos 8. If you install IBM Cognos 8 in new locations, you must update the locations using IBM Cognos Configuration.
If you are upgrading IBM Cognos 8 BI in an environment that includes earlier versions of other IBM Cognos 8 products, such as IBM Cognos 8 Controller 8.3, IBM Cognos 8 Planning 8.3, or IBM Cognos 8 BI Analysis for Excel 8.3, install the new version of IBM Cognos 8 BI in a separate location from the other IBM Cognos 8 product and configure IBM Cognos 8 BI to operate independently of that product. After you upgrade the other product to a compatible version with IBM Cognos 8 BI, you can then configure the two products to operate together.
For Windows installations, ensure that you have administrator privileges for the Windows computer you are installing on. Also ensure that your computer has a TEMP system variable that points to the directory where you want to store temporary files. During installation, files from the CD are temporarily copied to this directory.
For UNIX installations, you can install server components using a graphical user interface or by running a silent installation. To run graphical-mode installation, the console attached to your UNIX computer must support a Java-based graphical user interface.
Also, IBM Cognos 8 respects the file mode creation mask (umask) of the account running the installation program. This affects only the installation directories. It does not affect the file permissions within the directories. However, run-time generated files, such as logs, respect the mask. We recommend umask 022 on the installation directory.
If you want to use Cognos Content Database as your content store, you must select it in the installation wizard. If you are installing components on several computers, you need to only install one Cognos Content Database. If you install Cognos Content Database on the same computer as Content Manager, and you later decide to use another database for your content store, you must uninstall Cognos Content Database.
